The apparatus in the construction shown has at each end of the tank a leg or standard 1, each leg or standard havinga rearward extension at its upper end furnishing supports 2, which receive and carrv the filling-tank 3, one end of the tank having a solid head and the other end having a removable head to enable access to be had to the interior 'of' the tank for cleansing or otherpurposes. The filling-tank 3 can be made of metal or other suitable material and of the capacity desired and can be of a length to receive and support three or more filling appliances, one

of such apphanees, only being shown in Fig. the proper length to operate with a single filling appliance.

The end standards are connected on the front of the machine by a cross-plate 4, at tached to which are bracket-plates 5, having a vertical section or portion and a-horizontal section or portion, the atter ofwhjch has one-half 6 of a journal box or bearing, the other half 7 of the journal box or bearing be ing formed on a plate 8, attached to the horizontal portion or section of the bracket-plate. The journal boxes or bearings receive ournalpins 9, one at each end of a. frame 10, supporting the frame, SO tl18.l) it is free to have a rocking movement fore and aft. Each side sas,o57 7 8 bar of the frame 10has secured thereto by bolts or otherwise a plate 11, on which is a half-box or j ournal-bearing 1 2, the companion half-box or journal-bearing 13 being formed on the side plate orbar of the frame 10. The journal box or bearing of the frame 10 on each side has entered thereinto a journal 14, extending out from a plate 15, occupying'the space within the frame 10 at the lowerportion thereof. The plate 15 has depending therefrom s de bars 16, each terminating at its lower end in'a foot or head 17, and extending out from one foot or head 17 with a downward inclination is a bar 18, which is continued in a straight horizontal line by a bar 19, to which is connected on'e end of a bar 20, the other end of which is connected to. the opposite foot or head 17, so that the bars 18, 19,

and 20 form a cross plate or'head for the lower end of the frame composed of the 'plate15 and the side bars 16, which frame, by. means of the journals 14, has a side rock or swing; This arrangement-of-the frame' 10 with its end journals and the plate 15 with its side journals operates to allow both afore and aft rock and an end'rock for the frame or support as a whole, by which the sealing-head can be brought into position to aline with and operate properly to seal the bung or other filling hole in the to-be-filled package in the event of such bung or other filling h'ole being out of direct alinement with the sealing-head and the filling-tube.

A rod 21 is located adjacent to each side bar 16, and each rod 21 at its upper end extends through the plate 15 and is free to slide in said plate, and, as shown, at the upper end of each rod 21 is a collar 21, furnishing a support for a weEght, if needed, for the purpose of causing the sealing-head to descend by gravity in sealing the bung or other filling hole. A cross head or bar 22, having at each end a socket 22", is attached by the sockets and suitable set screws -or bolts 22 to the sliding rods 21 for' the bar 22 to be located when the parts are in normal position just below the plate 15, and this bar 22 moves with the sliding rods. lower end is secured in. an car 23 of a cross head or bar 23 andis held in place by a jamnut 24 and a lock-nut. 25, threaded onto the end of the rod on opposite sides of the ear. The cross head or bar 23 has an enlarged intermediate portion 26, having a central circular portion 27, on the upper side of whi. is

an annularflange 28, having an ext rior screw-thread, which receives a cap 29, Within which is a gland or follower 30, which 'compresses a packing-ring or gasket 31, enci'r? cling the filling-tube 32, so as to make a tight joint around the filling-tube and prevent the escape of pressure around the tube. The filling-tube 32 passes through the end of the bar or plate 19, and the cross bar or plate 23 as located below the cross-head at the lower Each rod 21 at its.

end of the side bar 16 so that the filling-tube is guided in its reciprocating movement by the plate 19. The under face of the circular head 27 of the cross bar or plate 23 has an annular rim 33, which receives a sealing-ring 34, of rubber or other suitable material, which sealin -ri ng encircles a bearing or guide 36, three ed into a hole in the head 27, so that the lower end of the sleeve or guide 36 projects bel w the edge of the sealing-ring, and this lower end of the sleeve or guide'is curved and forms a face by which the sealing-ring can be seated without liability of being jammed or knocked to pieces, as the curved outer face of the sleeve or guide 36 forms a guard and protection for the sealing-ring in the descent of the sealing-head to close the bung or other filling hole of the package. The sleeve or guide 36 on its inner face has a series of ribs 37, leaving passages 38 between the exterior of the filling-tube and the interior face of the sleeve or guide 36, which passages at their lower end furnish openings 39,

through which when the sealing-head is in the crossbar or plate of the head and terminates in a passage 42, leading upwardly into a chamber 43, encircled by an annular flange 44 on the cross plate or bar of the seal ing-head. A coupling-plug 45 is entered into the annular wall or flange 44 and has entered thereonto the lower ring or band 46 of a frame carrying a sight-glass, which frame has side bars 47, connectingthelower ring or band 46 with an upper ring or band 48, between which rings or bands 46 and 48 is located a sightglass 49,'held in place by coupling-heads 50, as usual in the construction of sight-glasses. The upper band or ring 48 has a side extension 48*, into which is entered the lower end of a tube 51, the upper end of which has attached thereto one end of a hose 52, the other end of which hose is connected to a plug 53, entered into the upper side of the filling-tank 3, so that I pressure from the upper portion of the fillingtank can flow through the hose 52', tube 51, sight-glass 50, and passage 41 into the chamber 40 and from the chamber 40 flow out through the channels or passages 38 and openings 39 into the to-be-filled package, and pressure from the to be-jilledpackage can flow back through the openings 39, channels or passages 38, 1 chamber 40, passage 41, sight-glass 50, tube 51, and hose 52 into the upper portion of the filling-tank. The induction of pressure from the fillingtank into the to-be-filled package occurs when the sealingring has effectually sealed the bun or filling hole of the package, and this in notion of pressure from the tank into the package adds of the to the normal pressure in the package an amount of pressure from the tank to equalize the pressure between the tank and the to-befilled package, and the induction of pressure from the to-be-filled package back into the filling-tank occurs asthe liquid flows intopower with the liquid in the tank at normal height, as hereinafter described, for operating the piston bywhich the filling-tube is raised and lowered.

The upper end of the filling-tube is entered into an annular rim orflange 54 on the under side of a head 55, and the lower end of the filling-tube is closed by a valve 56 on the end rod 57, the upper end of which rod is connected by a pin or pivot 58 to an arm 59 within the head 55, which armis mounted on a rock-shaft 60, supported in the side walls of the head 55 with its ends projecting beyond the side walls of the head and having secured thereto an arm 61, the outer end of which straddles one of the sliding rods 21, and this arm 61 is held normally depressed, so as to hold the arm 59 in a raised position and close the valve 56 by a spring 62, attached to 'studs or pins 63, projecting out from the exterior face of the head 55 in the construction shown. The descent of the head 55 with the filling tube 32 carries down with it the arm 61, and when the filling-tube has descended to a point where the under fact) of the arm 61.

contacts the foot or head 1.7 the further downward movement of the head. 55 and the filling-tube will raise the arm 61, rockin the shaft to carry down the outer end 0? the arm 59 and force the valve 56 away from the lower end of the filling-tube, allowingthe liquid to pass through the filling-tube and flow into the package.

The upper side of the head 55 has thereon a boss 64, in which is secured the lower end. of a piston-rod 65. which rod passes 11 p through the plate 15, and its upper end has secured thereto a piston (56, which traverses a cylinder 67, closed at its upper end by a cap or head 68 and entered at its lower end into an annular flange 69, secured to the plate 15 and in communication with a chamber 70, formed in the plate, which chamber has leading out therefrom, through one of the journals 14, a passage 71, into which is entered the end of a tube 72, the other end of which is connected with the casing of the main controlling-valve. A tube 73 leads from the op- Eosite side of the casing of the main controlng-valve and extends upward and is entered petcock 74 connected port the exhaust is discharged.

into the top plate or cap 68 of the cylinder, so that pressure can be admitted to both ends of the cylinder and on opposite sides of the piston for the pressure 011 the upper side to force tihefpistori down and with it the head 55 and the lling-tube 32 and for the pressure on the under side to raise the piston and with it the head 55 and the filling-tube. The tube 72 and-the tube 73 each have a therewith, and by pctcocks the interior of the can be lubricated without any trouble. The lubrication of the cylinder on the under side of the piston is attained by opening the lower petcock when the piston 66is at the limit of its descent and pouring the lubricant into the-pipe 72, so'that with the upward movement of the piston 66 the lubricant will be sucked into the interior of the cylinder, and when the limit of upward movement isreached by closing the petcock the lubricant will be kept in the cylinder. The lubricant is supplied to the cylinder above the piston 66 by opening the upper petcock when the piston is at the limit of its upward stroke and pouring in the lubricant, so that on the downstroke of the piston the-lubricant will be drawn into the interior of the cylinder and will remain therein when the means of these cylinder 67 petcock is closed. It will thusbe seen that 5 the lubricating of the piston is attained with out any trouble or inconvenience and through the suction of the pistonin the cylinder.

The main controlling=valve has an outer shell or casing 75, into which is entered the ends of the tubes 72 and 73 as shown in Figs. 8, 9, and 10, and this shell or casing 75 has therein a plug 76, in the body,of which is a passage 7 7 and a passage 78, so arranged as to be brought into communication with a port 79, leading through the casing from the tube 72, and a port 82, leading through the casing from the tube 73 and also to be brought into comm nicationwith a port 81, leading through the .casing, througrh he passages 77 and 78 also furnish communication between the ports 79 and 80 and a'port 82, which is in communication with a tube-83, leading upward and connected in the arrangement shown with the end of a hose 84, the other end of which is connected with a nipple on the main pressure-supply pipe 85, which pipe has coi'nnmnication also with the interior of the filling-tank 3 at a point above the level of the liquid in the tank, so as to furnish the upper portion of the tank with the requiredamount of pressure.

The main shell or casing 75 at its inner end has'a threaded stem 86,- by means of which the valve as a whole is attached to one of the side bars 16 of the swinging frame. The

, plug 76 has a stem 87, having adjacent to the end of the plug a shoulder 88,- against which abuts a disk 89, encircling the stem, and the which disk 89 is attached to the end of the main shell or casing by draw-bolts 90, soas to hold the plug in place within its chamber in the required for admitting pressure to the upper end of the cylinder 67 and exhausting pressure from the lower end of said cylinder or for admitting pressure to the lower end of .aid' cylinder and exhausting pressure from the upper end of said cylinder. -The pressure admitted to the upper end of the cylinend of the cylinder 67 operates tolift the package. I The plate or head 26 on one side of the cenxtefhead 27 has formed therein a tapered opening or "chamber 98, which crosses the passage 41, and this chamber 93'has entered thereinto a shell or sleeve 94, having a tapered exterior and interior. The shell or sleeve-94 at its base end has a lip or projection 95, whichenters a slot 96,- formed'in'a rim around the chamber 93, bywhich the shr ll or sleeve is held in a fixed relation when entered into the chamber, and this lip or proj ction 95 forms on its inner edge a stop 97, a companion stop 97 being formed on the edge of the she ll or sleeve, which stops limit the turning of the plug Within the shell or casing. The apex end .of the shell or casing 94 has an extension 98 with an exterior screw-thread, which receives a ring-nut 99, by means of which the shell or casing 94 is held within the chamber 93, so as to receive the plug of the valve. The plug 100 of the valve entered into the interposed shell or casing94 and is h ld in the shell or casing by a washer 101 at its a'p'- x end, which abuts against the facefof the ring-nut 99 and is" held "in place bya screw 102,the stem ofwhich threads into the end of the plug 100, holding the ;plug against end mow-"ment. The basc end of the plug 100 has tlvr; on stop-pins -9 71 -to coact with the-stops 97 and limit, the'.-turning of the plug, and extending out from the base end of the plug is a stem 103, theexti'c-meend of which is squared to receive a socket 1040f an arm or ii v-r-r 105, having at its outer end a pin or pivot 106, to which connected thelower end of a bar 107, towhich bar is connected 'by pins or pivots 108 a s ries of trip-arms 109', and the rear end of each trip-arm 109 is p attached by a pin or pivot-11011.0 a fixedbari 111, attached at its upper end to the cross head or bar 22 of the reciprocating frame and at its lower end to the cross bar or plate'23 of the sealing-head. The inner end of each trip-arm 109 has a lateral wing 112, with an inclined up er and lower face, which faces are engage by the ends of trip-fingers carried by the head 55 of the filling-tube. The inclined upperface of the engaged trip-arm 109 is contacted by the end ofa trip-finger 113 on the descent of the head 55 with the descent of the filling-tube, and the inclined under face of the engaged trip-arm is contacted by the end of a trip-finger 114 on the upward movement of the head 55 with the raising of the filling-tube. The tri -arm 113 has in its body a slot 113, into w ich is-entered the st'eni'114 of the trip-finger 114, and both trip-fingers are mounted on a pivot i or pin 115-between ears 116 on the head 55,

The acting end of the trip-finger 113 is held in its of a tail OYBXtOIlSlOIl 117 of its body with the face of the head 55, and the acting end of the f normal projected position by the engagement piston 66 and raise the filling-tube out of the I trip-finger i1 14 is held inits normal projected position by the engagement of a tail or extension- 118 of its body with the end face of the head 55, so that the acting ends of both fingers are normally held in position to strike the contact-face of'the tri -arm 109 which is engaged by the finger. T e body of the tripfinger 113 has on its rear face a socket 119,

into which is entered the end of a coil-spring 120, the other end of which bears against the face of the head 55 for the spring to act and hold the acting end of the trip-finger in its projected position and at the same time allow of the necessary yield for the acting end to pass the wings of the trip-arms after the, arms have been carried down by the engage- TOO ment of the acting end of the trip-finger 113 with the first trip-arm. The trip-finger 114 has on its rear face a socket 121, into which isentered one end of aspring 122, the other end ofwhichengages the face of the head 55 for the spring to act and hold the tri -finger in its normal pr'o'ected position an at the same time allow of the necessary yield for the finger to pass the lateral wings of the triparms 109 after the trip-arms have been raised by the engagement of the acting end of the trip-finger 114 with the lowermost trip-arm. Y

The construction shown has pipe 123 leading from a source of pressure-supply, such as an air-compressor or a tank containing compressed air, and this pipe 123 leads into a pressure-regulator 124, from which a pipe 125 leads to the supply-pipe 85, which pipes can have thereon a gage 126 for indicating a side and has connected therewith a hose 128,

the other end of which is ,connected .to a 7 will not have to traverse the length of the 55 coupling 129 on the head 55, so that the beer cylinder, as in the case of a full-sized packor other liquid can fiow 1 from the tank age.

passage-42 into the sight-glass to return through the tube 51 into the upper portion of the fillingetank, creating a pressure in such tank equal to the amount of air normally present in the to-be-filled package before the pressure is equalized between the filling-tank and the package with the added pressure from the tank to the package for equalizing the ressure. ize as the ower for operating the piston 66 to raise and lower the filling-tube. The liquid flowing into the package as the package becomes filled passes up through the openings 39, passages or .channels 38 into the chamber 40 and through the passage 41 and passage 42 makes its a pearance in the sightglass, and when the liquid is showninthe sightglas's the operator reverses the handle or lever 92, turning it back, so as to establish communication between the passage 77 and ports 79 and 82 for pressure to flow from the tank through the pipe 83 and pipe 72 into the cylinder 67 below the piston and at the same time to open communication between the port 80 and port 81 through the passage 78, allowing pressure to vent from the upper portion of the cylinder 67 above the piston for the pressure below the piston 66- to operate and through the piston stem or rod raise the head 55 and filling-tube. The initial upward movement of the head 55 and filling-. tube causes the end of the trip-finger 114- to strike the wing 112 of the lowermost trip-arm 109, raising such arm, and with it the bar 107, for the upward movement of the bar through the arm or lever 105 to turn the plug 100, carrying the port 41 therein out of alinement with the-port 41 and passage 41, shutting ofi' communication between the chamber and the chamber 43, and the further the head and the fillmg tube. full withdrawal of the filling-tube the frame upward movement of the filling-tube and its head 55 does not affect the position of the plug 100, as the end of the trip-finger 114 will strike the under inclined faceof the wings above the lowermost one without changing the position of the plug, which remains closed during the continued u ward movement of,

carrying the sealing-head and filling-tube 'is' swung rearward, so that the operator can insert a bung and close the package and when closed the filled package is rolledofi from the support and a new package placed in position,

which package is to be sealed b the descent of the sealing-head and the fil lug-tube entered thereinto, and the operation just de scribed repeated, such operation bemg'con tinned until the required number of packages have been filled.

The same operation is had infillingsmaller- This returned pressure is util- After the;

and with a half barrel or package the fillingtube and the sealing-head can be operated as described for a full barrel or package, if so de sired, though if it is not desired to have the filling-tube make 'a full movement in entering and withdrawing from-the package a stopblock' of the proper length can be inserted around the piston stem or rod, so as to limit the upward movement of the filling-tube at a point to just clear the top of the half barrel or package, and, with the stop-black, the trip-finger 113 will first engage the second trip-arm from the top instead of the first triparm; but otherwise the operation will be the same. The filling of a quarter barrel or package is attained by using a stop-block around. the piston rod or stem, such stop-block being of the requisite len th to limit the upward movement of the ii ling-tube at a point'to clear the top or upper side of the quarter barrel or package, and when this is the case .the

trip-finger 113 will operate on the third tripv arm from the top one; but otherwise the operation will be the same as described for a full barrel or package. The fillin of an eighth barrel or package is attained by using a stop-block around the piston stem or rod of sufiicient len th to limit the upward movement of the filling-tube at a point to clear the 9 top or u per side of the eighth barrel or pack-' age, an when this is the case the trip-finger 113 will operate on thelowermost or fourth trip-arm; but otherwise the operation is the same as described for a full barrel or package.

The air originall vcontained in the to-befilled package cannot escape after the package is sealed, and this original amount of air,

with the added pressure from the tank to out requiring additional pressure to be supplied to the. upper ortion of the tank. It is preferred to mitia y charge the tank with "and maintain-in thetank from a source of pressure-supply the required amount of pressure, as by so doing-the tank'will contain a suflicient amount of pressure for"operative purposes, so that the added pressure from.

the to-be-filledpackage compensates for the pressure which isuti ized in operatin the piston by which the filling-tube is raised and owered.

It is possible tostart the a paratus without other pressure than that erived from. compressin the air in the tank in supplying the liqui to .the tank for use, and

when the apparatus is so used the necessaryv pressure for operating the piston by which the filling-tube is raised and lowered is obtained from the added pressure forced into the tank from the package as the package is filled with liquid, and after pressure suificient for the purpose is once obtained such pressure will be maintained so long as the ma chine is operated in filling packages. It will be seen that the apparatus is capable of operation without a constant supply of outsi e pressure and that when the apparatus is once under pressure the air-pump, if used, or other source of pressure-supply can be cut out and the machine operated while the packages are filled with the liquid, as the flow of the liquid from the filling-tank into the packages furnishes an amount of pressure suflicient to com ensate for the pressure used to operate the 'lling-tube, thus dispensing with outside power and using no other power than that derived from the pressure forced from the package back into the filling-tank as the package is filledwith liquid.

The operation of the apparatus is controlled through a single handle or lever, by which the operator can turn the main pressure-controlling valve so as to open communication between the tank and the cylinder of the piston for raising and lowering the fillingtube as may be required to supply pressure to one end of said cylinder and exhaust pressure from the other end, so that the attention of the operator is only required for the one valve. The valve controlling communication between the filling-tank and the sealing- I head is automatically operated With the forcedoilt in each ling-valve for the communication between f movements of the filling-tube, with the result that at the initial descent of the fillingtube communication is opened between the filling-tank and the to-be-filled package to equalize the pressure between the tank and the package, and this communication remains open until the package is filled with the liquid, and when filled the operator reverses the main pressure-controlling valve to raise the filling-tube, the initial movement upward of the filling-tube closing communication between the sealing-head and the filling-tank, preventing the escape of pressure from the tank and the admission of liquid into thesight-glass. 'lhesmall amountof liquid which flows into the sight-glass is instance When the controlthe filling-tank and the to-be-filled package is opened to equalize the pressure, and this small amount of liquid does notafiect in the least the equalizing of the pressure between the filling-tank and the to-be-filled package.
